The following KBs are checked:
The patch version is 11.0.14393.1198(KB4019472)
The patch version is 11.0.15063.296(KB4016871)

Consequence

Successful exploitation of the vulnerability may allow the attacker to cause:

QID Detection Logic (Authenticated):
This QID reviews the Windows build number under the registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion.
The QID is posted if the vulnerable build number "10240" is found on a Windows 10 target.

Consequence

The system is at high risk of being exposed to security vulnerabilities.
Since the vendor no longer provides updates, obsolete software is more vulnerable to viruses and other attacks.

These new vulnerability checks are included in Qualys
vulnerability signature
2.4.35-4.
Each Qualys account is automatically updated with the latest
vulnerability signatures as they become available. To view the
vulnerability signature version in your account, from the
Qualys Help menu, select the About tab.

Selective Scan Instructions Using Qualys

To perform a selective vulnerability scan, configure a scan profile to use the following options:

Ensure access to TCP ports 135 and 139 are available.

Enable Windows Authentication (specify Authentication Records).

Enable the following Qualys IDs:

100311

100310

91371

110298

91370

91369

105718

If you would like the scan to return the Windows Hostname, also include QID 82044 and ensure access to UDP port 137 is available.

If you would like to be notified if Qualys is unable to log on to a host (if Authentication fails), also include QID 105015.

In addition, prior to running a scan for these new vulnerabilities, you can estimate your exposure to these new threats by running the Risk Analysis Report, available from the Qualys Vulnerability Management Reports tab.
